Passo di Gavia (Gavia Pass)
Passo di Gavia (Gavia Pass) is a high mountain pass in the Italian Alps. It is the tenth highest paved road in the Alps.
The pass lies in the Lombardy region and divides the province of Sondrio to the north and the province of Brescia to the south. The road over the pass (SS 300) connects Bormio to the northwest with Ponte di Legno to the south and is single track most on its southern section.
Passo di Gavia is often on the route of the Giro d’Italia road bicycle race and is sometimes designated the Cima Coppi, the highest point of the race. On 5 June 1988, the race passed over the Gavia in a snowstorm, making for an epic stage won by Erik Breukink. AmericanAndrew Hampsten, the second place finisher, became the overall race leader and went on to win the Giro.
Passo dello Stelvio
Passo dello Stelvio (The Stelvio Pass) located in Italy, at 2757 m (9045 feet) is the highest paved mountain pass in the Eastern Alps, and the second highest in the Alps, slightly below the Col de l’Iseran (2770 m, 9088 feet).
Passo dello Stelvio retains an importance for cycling when it is open from June to September. Countless cyclists struggle to get to the highest stretch of road in the Eastern Alps. It is the highest finish of any Grand Tour. The Giro d’Italia often crosses the Stelvio Pass (it was crossed by the Giro for the first time in 1953, when Coppi beat Koblet). The last winner on the pass was Thomas De Gendt in 2012. Every year, the pass is closed to motor vehicles on one day in late August when about 8000 cyclists ride on the Stelvio. (wiki)
